Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484366, here are decompositions:

3 + 31484363 = 31484366
7 + 31484359 = 31484366
13 + 31484353 = 31484366
127 + 31484239 = 31484366
157 + 31484209 = 31484366
163 + 31484203 = 31484366
223 + 31484143 = 31484366
307 + 31484059 = 31484366

Showing the first eight; more decompositions exist.
